Subatomic Particles

Subatomic Particles

Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

Atomic Structure

Atomic Structure

The Greek philosopher Democritus proposed that everything on Earth is made up of tiny particles called atomos, Greek for "indivisible," from which the modern term "atom" is derived. In the 19th century, John Dalton proposed the atomic theory that is still largely correct today. He put forth five postulates to explain how atoms made up the world around us. (1) All matter is composed of infinitely small particles or atoms. (2) All atoms of a given element are identical to one...

Colloidal precipitates

Colloidal precipitates

The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

Electronic Structure of Atoms

Electronic Structure of Atoms

An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...

The Quantum-Mechanical Model of an Atom

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Area of Science:

Supramolecular chemistry and materials science.
Colloidal self-assembly and hierarchical structures.

Background:

Complex materials often exhibit hierarchical organization across multiple length scales.
Supracolloidal structures arise from the assembly of macromolecules and supramolecular aggregates.
Controlling these assemblies requires specific interactions between colloidal entities.

Purpose of the Study:

To engineer bile salt derivative-based supramolecular tubules for controlled hierarchical self-assembly.
To investigate the specific interactions between these tubules and polymeric microgel spheres.
To develop stimuli-responsive supracolloidal systems.

Main Methods:

Design and synthesis of customized bile salt derivative supramolecular tubules.
Utilizing the scroll-like structure of tubules for specific interactions with microgel spheres.
Triggering supramolecular assembly using pH and temperature stimuli.

Main Results:

Hierarchical supracolloidal self-assembly of microgels and supramolecular scrolls into a regular framework.
Formation of a 'nodes' and 'linkers' structure analogous to metal-organic frameworks.
Demonstration of stimuli-responsive properties in the assembled supracolloidal system.

Conclusions:

Engineered supramolecular tubules enable precise control over supracolloidal assembly.
The developed system exhibits hierarchical organization and stimuli-responsive behavior.
This approach offers a pathway to creating complex, functional materials inspired by nature.
